I'm really not confident with Regex, I know some basic syntax but not enough to keep me happy.

I'm trying to build a regular expression to check if an email is valid. So far here's what I've got:

[A-Za-z0-9._-]+@[A-Za-z0-9]+.[A-Za-z.]+

It needs to take account of periods in the username/domain and I think it works with multiple TLDs (e.g. co.uk).

I'm working with the preg engine in PHP so it needs to work with that. Thanks if you can help!
